They don’t have to tip toe around puddles in our funky kids’ wellies, they can splash right in! Cute and colourful, these striped wellingtons bring some cheer to even the greyest of days, and with a grip sole little ones can enjoy secure hold on wet surfaces. A super pretty and fun way to still dress sensibly for wet weather, these wellington boots come with two neat handles on each boot, so they’re easy to carry and hang to dry or store.
